This game is kind of a rejiggering of the Sonic 3D Blast concept, packed down to fit on the humble Game Gear. Sonic rolls around in various labyrinths (which aren't actually all that mazelike) finding keys to open the exit whilst trying not to get spooged on by robots. You can only actually move in four directions, which makes the game feel clunky. Isn't as completely terrible as its reputation has it, but certainly not very good.
